spiral
n.— «After three spirals spanning five months, the main experiment for the Joint Expeditionary Force Experiment 2006 is finally under way here.…According to Scott Sampson, execution director, JEFX consists of three spiral events and a main experiment. Spiral 1 is essentially a technology demonstration of the command and control tools or “initiatives” where warfighters provide feedback to developers which the developers use to modify the initiative before Spiral 2 and 3. During Spirals 2 and 3, the warfighters, manning an operationally representative combined air operations center, use the initiatives and systems, assess them for their operational utility and submit desired changes.» —“Main experiment under way for JEFX ’06” by Ross Tweten in Nellis Air Force Base, Nevada Air Force Link Apr. 21, 2006.
